• BRIGHT AND EFFICIENT: Compared with other LED bulbs, SANSI's highly efficient light bulbs can provide 5500 lumens using only 36 watts of power, equivalent to 350W incandescent bulbs. Based on 3 hours per day usage, save up to 95 percent electricity, annual estimated cost 3.94 dollars. FLICKER-FREE: Adopting high light transmission optical lenses, up to 126 LED chips can not only provide you and your family with the light source they need daily but also provide a healthy living or work environment. No flickering, no noise. PATENTED CERAMIC TECHNOLOGY: SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, directly soldering the LED chip on the ceramic heat sink, effectively reducing the systematic thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, making SANSI's bulbs perform with higher light efficiency. EXTEND THE LIFESPAN: The temperature of the LED bulb made of ceramic material is very low when it is working, and its flame retardancy and heat resistance are better, it is not easy to cause the aging and yellowing of the lampshade, and it will look like new after long-term use, with better heat dissipation performance and longer service life. GUARANTEES: ETL listed, quality and safety verified, 22.5 years LED bulb lifespan, 5 years warranty., Weight: 0.67902376696 Pounds, Manufacturer: SANSI
